A forklift truck has weight ω2 and is used to lift a crate with center of gravity G1 and weight ω1.
(a) If the center of gravity of the forklift truck is located a distance x in front of the rear wheel, determine an expression for the reaction force at each of the wheels as a function of the problem parameters d1, d2, w1, w2, and x.
(b) What is the maximum weight that can be lifted without the truck tipping over?
(c) You and your friend were using this forklift and realized that you had to lift a weight that was above the limit given in part
(b). What could you do to get your task completed?
